Which statement about the specific immune response is FALSE? Each T or B cell has antigen receptors for only one specific antigen.
T and B cells recognize antigens by using antibodies bound to their surface membranes.
Unique antigen receptors are created by genetic recombination.
Antigens must be presented by an MHC molecule for T and B cells to recognize them.
All cells express MHC-I molecules, but only antigen-presenting cells express MHC-II molecules.

autosomal

explanation:

is a term used in genetic genealogy to describe dna which is inherited from the autosomal chromosomes

format change of dna.  

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.
